IMPROVEMENT IN SEAMS FOR BOOTS AND SHOES.

Specification forming part of Letters Patent No. 175,278, dated March28, 1876; application filed January 17, 1876.

art or science to which it most nearly apper tains to make and use mysaid invention or improvement without further invention or experiment.

My invention relates to an improved mode of forming Welts and stays forprotecting the seams in bootsand shoes; and it consists in utilizing thesingle edges of a double. welt so as to make them serve as stays on theinside of the seam.

Referring to the drawings, Figure 1 is a view showing my device. Fig. 2is a section of the welt.

The seam to which this welt is applicable in the manufacture of bootsand shoes is where two raw edges are to be united together. I11- steadof using a single thickness of leather to form the Welt, I take a strip,0, of leather, cloth, or other material of which the welt is to be made,and fold it double lengthwise, and in applying it I place this doubledstrip between the edges to be united, and sew it in place, so that itsdoubled edge will project slightly on the outside, While its singleedges are on the inside of the seam. I then fold the single edges'of thestay-piece in opposite directions,

and sew them down by a row of stitches on each side of the welt, so thatthese inside edges will form a stay for the seam. An independentstay-piece, d, can be used, if desired, but when it is used I place itover the inside of the seam, after the edges of the staypiece have beenfolded back, and the same row of stitches that is used to fasten theedges of the stay-piece down will serve to secure both the independentstay-piece and the edges of the Welt-piece. I thus provide a doubledwelt, which will not only be neat in appearance, but will projectslightly above the cloth, and protect the stitches upon each side fromthe wear to which they are subjected by the friction of the lower edgeof the dress of the wearer chafing over it, and at the same time thewelt-piece forms a stay for the seam, both welt and stay being combinedin the same piece or strip of leather.

Having thus described my invention, what I claim, and desire to secureby Letters Patent,

A combined welt and stay for the seams of boots and shoes, formed of thefolded strip 0, and applied so that its doubled edge forms the welt,while its single edges form stays in the inside of the seam.substantially as and for the purpose described.
